給wordpress創建帳號用
MariaDB [(none)]> create database wpdb;
MariaDB [(none)]> grant all privileges on wpdb.* to wpuser@'192.168.99.%' identified by "123";
創建帳號給ProxySQL監控用
MariaDB [(none)]> grant replication client on *.* to monitor@'192.168.99.%' identified by '123';
創建帳號用來ProxySQL訪問的(沒寫錯，這里真的還是4)
MariaDB [(none)]> grant all on *.* to sqluser@'%' identified by '123';

[LVS]$ ip route del default via 192.168.99.2[LVS]$ ip route add default via 192.168.99.101
安裝ipvsadm
[LVS]$ yum -y install ipvsadm
設置回環網卡地址
[LVS]$ ip a a 192.168.99.100 dev lo
配置LVS
[LVS]$ ipvsadm -A -t 192.168.99.100:80 -s wrr[LVS]$ ipvsadm -a -t 192.168.99.100:80 -r 192.168.99.103 -g -w 1[LVS]$ ipvsadm -a -t 192.168.99.100:80 -r 192.168.99.104 -g -w 1
下面2個設置在webA和webB上都要配置 4. 設置webA和webB的路由和arp設置
ip route del default via 192.168.99.2
ip route add default via 192.168.99.101
配置103和104(web服務A和B)，記得，2個主機都要這么配
echo 1 > /proc/sys/net/ipv4/conf/all/arp_ignore
echo 1 > /proc/sys/net/ipv4/conf/lo/arp_ignore
echo 2 > /proc/sys/net/ipv4/conf/all/arp_announce
echo 2 > /proc/sys/net/ipv4/conf/lo/arp_announce
